1. carbon-fibre composite, it comprises elastomerics and the carbon nanofiber that is dispersed in this elastomerics, wherein this elastomerics has unsaturated link(age) or the group that affinity is arranged with described carbon nanofiber at least one of its main chain, side chain and terminal chain, described unsaturated link(age) or group are to be selected from two keys, triple bond, carbonyl, carboxyl, hydroxyl, amino, itrile group, ketone group, amide group, epoxy group(ing), ester group, vinyl, halogen group, urethane ester group, biuret groups, at least a in allophanate group and the urea groups, andWherein the elastomerics in described matrix material is its non-crosslinked form, and under 150 ℃

  • , use the PULSED NMR technology, measure by the Hahn-echo method, the described elastomeric first spin-spin relaxation time is 100~

    3000 μ

    sec, not having the second spin-spin relaxation time or the second spin-spin relaxation time is 1000~

    10000 μ

    sec, and the mark of composition with second spin-spin relaxation time is less than 0.2.
